No worries dude I probably didn't read your post properly
My tip is a high pass between 60 - 80
If it needs brightness give it lots of 8k, as much as 6 db if you have (I learnt that years ago from a Chris Lord Alge interview)
Buss all rhthym guitars and limit or compress them just a little. Adjust the attack to let some transient through
Boost around 100-120 if you want more note definition
If it's too bright use a high shelf and not a bell eq
bell eq to take out nasty fequencies, shelves to do more general tone shaping
Also try and get as close as you can with eq on the buss instead of each track separate.
For years I tried to use every plugin I had, and these days I use almost nothing and my mixes improved heaps
